VIDEO: Zephyr Teachout won't rule out primary against Cuomo

Zephyr Teachout didn't rule anything out about her future political plans, leaving open the possibility that she could challenge Gov. Andrew Cuomo in a Democratic primary.

Both Cuomo and Teachout are Democrats who are seeking the Working Families Party line. Under New York's fusion voting rules, a candidate has to get 50 percent of the weighted vote of party leaders to obtain a ballot line of a party they aren't a member of.
